HORSE HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 727,154, dated May 5, 1903. Application filed June 16, 1902. Serial No. 111,967. (No model.)

new and useful Horse Hay-Rake, of which the following is a specification.

This invention is an improved horse hayxo rake of that class commonly known as pushrakes, in which the rakerhead is arranged in front of the horses and which are used in hayfields for conveying hay from cocks or windrows to a stack and for other similar purr poses; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

One object of this invention is to eflect improvements in the construction of the rakehead whereby the same is greatly strengthened and is adapted to be used for raking and moving heavy hay without becoming strained and without sagging.

A further object of this invention is to pro-- vide improved means for tilting the rake-head to raise and lower the points of the raketeeth.

In the accompanying drawings, Figure l is a top plan view of a rake constructed in accordance with this invention, the same being shown adapted for use as a rear-hitch rake. Fig. 2 is a side elevation of the same, showing the rake-head tilted to lower the points of the rake-teeth. Fig. 3 is a similar view of the same, partly in section, showing the rakehead tilted to raise the points of the raketeeth. Fig. 4 is a detail sectional view showing the means for tilting the rake-head to raise and lower the points of the rake-teeth,

0 the lever, gravity-dog, and link-dog being shown in the positions assumed thereby when raising the points of the rake-teeth. Fig. 5 is a similar view showing the lever turned rearwardly and the gravity-dog and link-dog 5 disengaged from the operating-bar to release the latter, and hence permit the points of the rake-teeth to drop to the ground. Fig. 6 is a similar view showing the lever moved forwardly to engage the gravitydog in such cross-bar 3 at the center thereof.

manner with the operating-bar as to cause the points of the rake-teeth to be pressed downwardly on the ground. Fig. 7 represents a perspective view taken from the rear of the machine.

The construction of the rake-head is as follows:

The rake-teeth l have their rear ends secured to the under side of a transversely-disposed bar 2, which forms the rear side of the rake-head. A cross-bar 3 is disposed at a suitable distance in advance of the rear crossbar 2 and bears on the rake-teeth, the latter being also secured to said cross-bar A pair :of vertically-disposed posts 4 rise from the ends of and are secured to the cross-bar 3, and

the upper ends of the said posts are connect-- ed together by a transversely-disposed platebar 5. The ends of the said plate-bar project outwardly beyond the said posts 4 for a bolted or otherwise secured on the rear crossbar 2 and their front ends bolted or otherwise secured on the ends of the cross-bar 3, between it and the posts 4. A truss-post 7 has its lower end secured to the front side of the Said trusspost extends above the plate-bar 5 and is also secured on the front side of the center thereof. An inclined brace-bar 8 has its upper end secured to the rear side of the truss-post near the upper end of the latter and its lower end secured to the center of the rear cross-bar 2. A pair of obliquely-disposed oppositely-inclined brace-bars 9 have their outer ends secured to the ends of said rear cross-bar 2 and their inner upper ends secured to opposite sides of the truss-post 7 near the upper end of the latter. A pair of oppositely-inclined 9o truss-rods 10 have their inner upper ends bolted or otherwise suitably secured to the truss-post 7 in the upper end thereof and their outer ends secured to the cross-bar 3 near the ends of the latter. The said trussrods bear at points intermediate their ends against the front side of the plate-bar 5 and are bolted thereto. A pair of brace-rods 11 have their upper ends secured on the platebar 5 near the ends thereof and theirrear ends secured to the ends of the rear cross-bar 2. It will be understood from the foregoing that the rake-head is braced and trussed in such manner as to render the same exceedingly strong, to prevent the same from getting out of shape, and to keep the rake-teeth in line with each other. The rake-head is provided with a pair of supporting-wheels which are disposed between the cross-bars 2 3 and at points intermediate the center and the sides of the rake-head. The bearings 13 for the said supporting-wheels are here shown as bolted to the under sides of those portions of certain of the rake-teeth which are between the cross-bars 2 3. It will be understood that by this disposition of the supporting-wheels between the center and the sides of the rakehead the stress of the load on the rake-head is distributed equally over the same. The trusses formed by'the truss-post, brace-bars, and truss-rods also serve to distribute the stress equally over the rake-head and to prevent the same from sagging either at its center or its sides.

A pair of coupling-bars lat, which diverge forwardly, have their front ends hingedly connected to the rear side of therake-head, as at 15. The rear ends of the said coupling-bars are secured to a bearing 16, in which are journaled the spindles 17 at the upper side of a fork 18, which carries the usual trail-wheel 19. The standard or bar 20, which carries the seat 21, has its lower end bolted or otherwise secured on the bearing 16. The seat is disposed directly above the trail-wheel. hen the rake is adapted for use as a rear-hitch rake, a transversely-disposed draft-bar 22 has its central portion secured on the couplingbars near the rear ends of the latter by clipbolts 23 or other suitable devices, whereby the said draft-bar may be readily detached. Brace-bars 24 are also provided, which have their front ends bolted or otherwise detach ably secured to the coupling-bars and their rear ends secured to the draft-bar. Said draft-bar and brace-bars 24 are shown in full lines in Fig. 1, and it will be understood that the singletres are attached to the ends of the draft-bar. Hence the team may be hitched tosaid draft-barbehind the rake-head. WVhen it is desired to use the rake, as shown in Fig. 7, as a side-hitch rake, the draft-bar and brace-bars 24 are removed and side-hitch poles 26, which are shown in full lines in Fig. 7, are employed. The said side-hitch poles are secured under the projecting ends of the plate-bar 5 and their rear ends are secured to the rear cross-bar 2. Draft-bars 25 will be used in connection with the side-hitch poles. The said draftbars 25 are secured to said side-hitch poles near their rear ends, are disposed obliquely with reference to the raketeeth, and their inner front ends are detachably secured on the cross-bar 3.

A transversely-disposed bar 27 of suitable length is secured to the under sides of the coupling-bars 14 near the rear ends thereof. On the central portion of the said bar 27 at a point between the said coupling-bars is secured a casting 28. The same is provided on its upper side with a pair of guide-lugs 29, suitably spaced apart, and is provided on its front side with a pair of forwardly-extending lugs 30. An operating-bar 31 has its front end pivotally connected to the upper end of truss-post 7. The rear portion of the said operating-bar bears on the casting 28 between the guide-lugs 29, and the said operatingbar is adapted to be moved longitudinally in opposite directions to tilt the rake-head in such manner as to raise or lower the points of the rake-teeth, as may be required. The operating-bar has notches 37 in its upper side and notches 41 in its lower side, as shown. A lever 38 has its lower end forked and disposed astride of the operating-bar. A linkdog 39 is pivoted at its front end in the fork of the lever 38 below the operating-bar. Said link-dog has a lateral offset near its front end, forming a shoulder 32, adapted to be engaged by the lever 38 when the latter is turned rearwardly. The rear portion of the link-dog is disposed between the lugs 30 of the casting 28 and is pivoted upon a bolt or pin 33, which connects said lugs and passes through an inclined slot 34 near the rear end of the link-dog. The latter has an upturned engaging point 35 at its rear end, adapted to enter the notches 41 in the lower side of the operating-bar, and is curved upwardly near its front end, as at 36, to bear under the opcrating-bar. A gravity-dog 45 is carried by the lever 38 and pivoted thereto at a point above the operating-bar by a bolt or pin 46. The said gravity-dog has a rearwardly-extending arm 43, having a foot-tread44; and a point 44 to engage a notch 37 in rear of the lever 38, and said gravity-dog also has a forwardly extending downwardly inclined counterbalancing-arm 45, which normally raises the rear arm of said dog and keeps the point 44 out of engagement with any of the notches 37. Said counterbalancing-arm has an opening 48, through which the operatingbar 31 extends and in which the same is adapted to slide, and said counterbalanciugarm is further provided with an engaging point 49 to enter the notches 37.

The operation is as follows: Initially, when the points of the rake-teeth are lowered the lever 38 will be turned forwardly, with the point 49 of the gravity-dog in engagement with one of the notches 37 on the operatingbar, so that the operator may, by means of the lever, hold the points of the teeth to the ground when the rake is being loaded by being drawn or pushed forwardly. When the lever is in this position, the link-dog is out of engagement with the notches 41 in the under side of the operatingbar. In order to raise the points of the rake-teeth after the rakehead has been loaded, the operator by placing one foot on the tread 4M depresses the rear arm of the gravity-dog, so that its point 44 engages one of the notches 37, and its point' 49 is released from the operating-bar.

The lever 38.is then pulled rearwardly to a vertical position, causing the same and the gravity-dog to draw the operating-bar rearwardly, the forward pull of the lower end of the lever on the link-dog causing the latter, by reason of its inclined cam-slot 34:. and the pin 33, to have its rear end raised so that the point 35 will engage one of the notches 4:1, and thus lock the operating-bar, so that the latter can support the rake-head and. the load thereon in an elevated position. -It will be understood that this operation of the lever 38 moves the operating-bar a distance equal to the space between two of its notches and that such operation must be repeated as many times as may be necessary to raise the point of the raketeeth to the required height. To disengage the link-dog 39 from the operating-bar, permit the latter to move forwardly, and the points of the rake-teeth to drop, the operator moves the lever 38 rearwardly from a vertical to an inclined position, thereby causing the said lever by engaging the shoulder 32 of 1 the link-dog to depress the rear end of the latter, so that its point 35 disengages the notch 41. This also causes the elevated portion 36 of the link-dog to bear under the operatingbar and prevent premature rengagement of the point 35 with a notch 41 thereof.
